Utterly amazing piece of kit, and came within 14 days. We were starting to panic, because all other transmitters were just not available for months, and then Dave at transmittersRus, got these wonderful TEM transmitters for us within 14 days. One of the most advanced and solid transmitters ever, with every facility you could ever want. Thanks to Dave at transmitterRus we were able to meet our deadline for our community radio station, otherwise we would never have got started for months. Thanks again to great service and mega advice from Dave.

Life a year later after using the TEM 100 watt transmitter: David at Transmitters ‘R’ Us suggested this wonderful TEM Opera Plus Transmitter for our community radio station Mighty Radio Southport. The thing about Community Radio is you need to stay on the air, and a transmitter failure can put you out of action for weeks. We have had transmitter failures, but NOT with this TEM Opera Plus transmitter. It has worked non-stop for almost a year now, it has never ever let us down. It has had to deal with a very hot summer, freezing winter (in a hut in a church), and just keeps on going. The web interface is easy to use, and so is the RDS interface (using Tiny RDS program supplied), all which can be controlled remotely (due to church access being difficult at most times), and the web control interface is always there for us – sending song titles and program info to the radio text part of RDS is a cinch. With other transmitter makes, the web interface often goes to sleep or crashes. This transmitter has been awesome, and I feel sure that after 12 months of use, this is the one to rely on. The transmitter has even had to deal with a storm damaged antenna and feeder cable, and has survived through it’s excellent protection circuitry, Thanks again to David for suggesting a brand I would have never ever heard of. The Italians certainly know what they are doing when it comes to one of the best and most reliable transmitters.
